Why is HTML5 an excellent option for playing slots in 2023?


HTML5 is a technology in demand in the gambling industry. With its help, they create cross-platform and safe games that gamers like and provide good traffic monetization for operators.

The pgdaveve.in review site has collected the best casino games in India based on HTML5. These titles are favorites for players from all over the world.

HTML5 in the gambling industry

HTML5 is the latest, fifth version of the hypertext markup language.

Tim Berners-Lee presented the technology in 1989; since then, it has been constantly improved by the world’s leading product companies. Google, Facebook, Microsoft, and other IT corporations work with HTML5 to improve the software environment and publish updates in the public domain.

HTML5 creates digital products in various areas, including healthcare, finance, law, and gambling. In addition, HTML5 entertainment is flexible, cross-platform, and has other great benefits.

The first HTML5 slots were presented in 2014, immediately after the release of the fifth hypertext markup language standard. The manufacturers have presented classic 3- and 5-reel slot machines with several fixed lines.

Over time, the decision mechanics have improved markedly. Cluster slots, games with built-in mini-rounds, machines with progressive jackpots, etc., began appearing in the top developers’ catalog.

At the moment, with the help of technology, create:

  • Slot machines;
  • board games;
  • arcades;
  • casual entertainment;
  • bingo and keno;
  • Lotteries with instant results (scratch cards).

Features of casino content development

HTML5 is a standalone programming language and an API for integrating additional IT solutions. For example, manufacturers can plug in 3D GUIs, animation tools, and other useful engines.

Most of the products are free, significantly reducing the cost of producing HTML5 content for online casinos.

  • CSS Cascading Style Sheets are an essential component of the technology. With their help, you can ultimately draw the layout of the slot machine without using external editors.
  • Hypertext Markup Language works in conjunction with JavaScript. It creates more complex games, such as shooters or multiplayer fishing.

Basic technology

A hypertext markup language is a basis for creating slot machines. The local canvas provides all the necessary functionality, from developing your game to running it in your browser.

HTML5 is responsible for the following:

  • placement of components on the playing field;
  • structuring data libraries;
  • quick changes and updates to the slot;
  • adaptation of performance depending on the speed of the Internet connection and much more.

Physical drives

They are used to create more advanced games, such as multiplayer solutions or slots with built-in mini-quests. Popular products include Box2D, Phaser, Construct Two and WebSockets. All of them are in the public domain.

Graphics rendering

Scope of application of graphic editors:

  • creation of animation, three-dimensional models, and other special effects;
  • work with audio;
  • access to hardware components (for example, GPS navigation or a camera built into a smartphone).

Well-known solutions include PlayCanvas, PixiJS, and ImpactJS.

Data Libraries

You can structure the program code and manage commands using HTML5, as well as using external libraries. Most often, specialists work with WebGL and CreateJS multifunctional products.


They turn a ready-made HTML5 game into a native application for placement in online stores and casinos. Manufacturers use Ejecta, PhoneGap, CocoonJS, and other programs.

The essential HTML5 tools are enough to produce full-fledged video slots and board games with a dynamic picture and improved mechanics. Engines and frameworks serve only as addition and automate technological processes.

Benefits of Creating HTML5 Slots

Let’s consider the main advantages of the solution for online casino operators and product companies (manufacturers and aggregators of gambling software).

Development cost optimization

HTML5 has everything you need to produce quality entertainment content from the ground up. For example, you can create 2D and 3D slots, arcade games, cards with a built-in random number generator, etc.

Additional tools (engines, wrappers), like HTML5, are in the public domain.

Product gambling companies do not spend money on:

  • rent payments;
  • license fees;
  • royalties and other deductions.

As a result, entrepreneurs optimize the cost of releasing digital content without sacrificing quality or performance.

High process speed

HTML5 solves the problem of backward compatibility 100% when content is first created in the underlying programming environment and then adapted to run in various plugins. In addition, the hypertext markup environment provides for simplified release and debugging of games, significantly reducing providers’ time.

Every browser (Chrome, Mozilla, Internet Explorer) understands HTML5 markup by default. As a result, casino software providers can adapt video slots to a specific user environment without months of painstaking work.

Operational distribution

Compiling, updating, and fixing bugs happen in a matter of minutes. The game can be published immediately after its development without preparatory stages and testing.

Placing HTML5 games in popular online stores (AppStore or Google Play) does not require special permission or subscription fees. Instead, it is enough to transform the game into a native application using free wrappers (Ejecta, PhoneGap, and others).

Distribution of content in social networks and instant messengers is also very convenient and, as a rule, does not involve additional costs.

Integration of promo tools

The use of technology solves the problems of retaining gamers, monetizing Internet traffic and increasing the duration of gaming sessions. HTML5 focuses entirely on these aspects, making it quick and easy to set up promo tools.

Slot machines implement:

  • jackpot series with a fixed and accumulative prize fund;
  • tournament series with leaderboards;
  • achievement races;
  • mini-rounds and bonus games;
  • sale of in-game tools and other options to motivate gamblers.

Focus on mobile development.

The fifth standard is supported and correctly displayed on all modern devices, including iOS, Android, and Windows Phones. As a result, professionals do not need to create multiple versions of entertainment for each operating system, which is convenient and cost-effective.

Simultaneously with the transition to HTML5 development, many providers have focused on mobile slots. As a result, smartphones provide about 70% of casino traffic, while desktop sites offer only 30% of the audience.
